Solve the problem of latex picture floating

problem ： Sometimes pictures are placed below the text , But in the end, it shows that the pictures are indeed behind the references . Referring to the information on the Internet , Most of the way is to add ：

\usepackage[section]{placeins}

But in this case, the picture will only be in section Inside , What we expect is the picture following the text . That is to follow subsection within . But there is no \usepackage[subsection]{placeins} Parameters of . therefore , You can add \FloatBarrier, So it won't float .

Here's an example ：

\usepackage[section]{placeins}

This is a passage .

\begin{figure}[t]
        include A picture .
\end{figure}

\FloatBarrier
